Specification of Letters Patent.

Application filed July 12, 1905. SerialNo. 269,398.

To all whom it nuty concern:

Be it known that 1, Euro H. REED, a citizen of the United States, residing at Wichita,

iiithe county of Qedgwick, State of Kansas, have invented certain new and useful Improvements in Convertible Molding-Mschines, of which the following is e. specification, reference being had therein to the accom enyingdrawings.

This invention relates to convertible molding-machine's, end articularly to a structure box may be used as a bottom face-mold, a ide face mold, or for brickmolding purposes. 1

The invention has for an object to provide an improved construction and arrangement of partsby which the side walls of a mold-box used for a bottom-face mold maybe adjusted to permit the, insertion of other side walls for use as a side-face mold or for brick mold ing purposes, thereby embodying in a single mschine a structure capable of performing seversl different moldingoperations by a simple adjustment of the parts.

A further object of the invention is to pro Vide an improved construction and arrangement of the side wall of the mold in connec tion with the bottom thereof whereby these parts are pivotally mounted to swing laterally of the mold, and thus remove the block therefrom. without the necessity of releasing or adjusting the remainingwalls of the mold.

Another object of the invention. is to provide an improved construction and arrangement' of division-pistes adapted to be atteched to the ordinary ()Ptllfitiilfittl'lUSi011 the cores, whereby the mold may be used for bricknnaking purposes.

Other and i i'ther objects and. advantagesoi'the .lIlVQlliJlOil will be hereinafter set forth, and the novel features thereof deiined in the eppended claims.

In the drawings, Figureil is a plan. of the mold provided with the side core-blocks. Fig. 2 is a central vertical erosssection thereof. Fig. 3 isa plan of the machine with "the .bi'iclsfoi'i1i.ing partitions or plates applied thereto. Fig. 4 is vertical section oi? the mold-box shown in. Fig. 3. Fig. 5 is a detail side well used in briclwnolding.

Like letters oi reference refer to like parts in theseverel figures ol' the drawings. The letter A designates heme or tsble of any desired construction having upon its upcomposed of the opposite end w lls'B adjuste'bly mounted upon the tabletop sy means of the bolts B extended through the slotted lugs B carried by the end walls. Atone side of the mold-box an adjustable side wall B is mounted and ads. ted for movement laterally toward and from t e endwallsso as to permit the insertion between it and the end walls of a supplemental well C, such sis-shown in Figs. 4: and 5, when used for briclcmold- 'ing. This adjustment may be accomplished Yetenteditpril 10, 19b6,,

in any desired manner-for instance ,by means of the lug Biresting on the table-top and secured by the bolt B", exte'nding'through a slot therein, as shown in Fig. 1.

In the construction sndiarra-ngement of parts shown. in Figs. 1 and 2 the mold. is adapted to form the face of the block upon the bottom thereof, and this bottom D is mounted in any desired menner at a right an gle to the reiniii 'eble side wall LJ. These parts D and l) are carried by angle-arms D and D respectively, these arms being pivotally mounted at D upon rock-shat t D, extending longitudinally of the mold oox. This shaft is curried by bearings l)", adjustably niminted on the top 01 the machine by means of lugs D and bolts D so as to Jermit a lateral movement of these arms, t hus shifting both the bottom and side wall supported thereby. This bottoin'D is supported from the arm. D by means of the sdjusting'screws D", by which it may be elevated and the depth of the mold-box determined, these screws being extended into apertures A formed in the top plate A of the table. The rock-shaft D" is provided at one end. with the operating-handle D of any desired consirucgles to their normal positions, thus com pletely removing the I'IlOlClGCl article from the box, so that it is readily accessible for removal from the machine by lifting the pallet or board carrying the same from the arm D The bearings stench end of the rock-shaft D are provided with vertically-cxtending plates 11, to which the supporting-rods E at opposite ends of the machine are secured, as shown in Fig. 1, these rods also passing through apertures in the relativelyiiMd side wallof theinold-box and are adapted to support the cores or divisiomplats cooperating with. the mold. In Fig 1 the cores E are adzipted to pass through apertures in the side of the operating-levers Ff, which are carried upon rock-shaft E mounted in suitable bear mgs 1n the frame A and provided at one end with an operating-handle E 10. Under some conditions of use it is desirable to elevate the bottom ofthe mold-box either for the purpose of assisting in ejecting the block therefrom, as shown in Fig. 1, or for bodily lifting the block, or diminishing the I capacity of the mold, as shown in Figt. For this purpose the follow-board or head F is mounted upona tubular shaft F, telescoping upon a rod F supported by the frame A beheath the mold-box thereon. This tubular 2o shaft is provided with a collar F secured .thereto and connected with a lifting-lever F by means of a pivoted link F, as shown in Fig. 2. The lifting-lever is mounted upon a rock-shaft F mounted in the frame of the 2 5 machine and provided with an operatinghandle F The follow-board may be. supported in its elevated position by means of a spring-latch F carried by this handle and provided with a laterally-extended end F fldQPtQdtOBDgSJgBa stop projection F carriedlbythe frame. When it is desired to per 'm'anently support this follow-board in its ele.

vated position-for instance, as shown in Fig.

, 4'.".t hecollar F carried by the rod F is adaptedto be adjusted thereon and secured at thefdesired elevation.

, -When it is desired to convert the machine from a bottom-face mold, as shown in Figs. 1

and 2, into a side-face mold, and one adapted 40 for brick-molding purposes, as shown in Figs.

3and 4, the bottom wall D and side wall D are thrown outward, as in position to deliver the material from the box, and adjusted away from the end walls B','so that the side wall C 5 may be inserted in contact with the end walls.

The opposite side Wall B is likewise shifted I laterally and a wall C introduced next the mold-box. These walls C are mounted upon the rods E and are provided With a series of slots or kerfs C C therein above the walls B and D, adapted to receive the division-plates C by which the mold is divided into proper' spaces for the formation of bricks from ce- -ment or similar material. These plates C iare mounted upon a cross-rod C provided with sleeves or collars C slidingly mounted iuponfthe supporting-rods E at each end of the machine,- and the cross-rod C extending to the slotted free end of the, lever E so as to shift theplates laterally of the mold-boX by i means of the handle E which is also adapted for the shifting of the cores when the latter are connected thereto. With the arrange.-

' ment of parts shown in Fig. 4 the cores are removed by simply releasing the same from the levers and withdrawing them from the supporting-rods. For molding bricks it is desirable to considerably reduce the depth of the box, and for this purpose the follower F is raised and secured in position, as shown in Fig. 4. i

In the operation of the machine it will be seen that with the parts arranged as in Figs.

1 and 2 the molding of blocks may be performed with the usual core-spaces therein and the face of the block upon the bottom of the mold-box, and after the withdrawal of the cores the block is immediately removed by swinging outward the pivotally-mounted side wall and bottom, so as to permit the ready, and convenient lifting of the block from the supporting-arms of the pallet or board which forms the side wall of the mold. When it is desirable to convert the machine into one for molding a block with itsface upon one side, this outwardly-swinging side wall and bottom may be thrown into the po-- sition shown in Fig. 4 and shifted away from the end wall, so as to permit the introduction of a fixed side wall, as shown at C, while for go brick-molding purposes the follower at the bottom of the mold is raised, so as to support the pallet or board carrying the material adjacent to the slots G, into which the divisionplates C are introduced, forming the bricks 9 5 of the desired size. After the material has been properly tamped and become set to the desired extent these plates are removed by the lever connected therewith and the board bearingthe completed bricks lifted from the I00 mold-box.

It will be obvious that the construction herein disclosed produces a single machine in which several molding operations frequently requiring the use of different machines may be successfully, conveniently, and economically effected.
